It's a secret to the person, but all the letters and accessories that I got from Shiho are stored in their own strongbox. The key on my necklace is for that strongbox. Kanon called it, "the nostalgic key"

Along with Shiho, Kanon is a student at Kanadenomiya Girls School. She's also part of the idol unit f*f.

Kanon is often described as a tsundere, meaning that she hides her true feelings being harsh towards her crush. Her teacher, Aoi, said that she's the type that goes for what she wants alone. Based on her bio we can say that when she sets a goal she goes for it doing her best, sometimes pushing herself too much.
